IMPROVEMENT IN APPLE-GRINDERS.

Specification forming part of Letters Patent No. 130,505, dated August 13, 1872.

' in the county of Oneida and State of New York.

The first part of my invention relates to the construction of the grinding-cylinder and the arrangement of the knives for cutting or grindin gthe apples, the former being formed of a succession of spiral staves or segments so put together as to leave suitable openings or interstices between them for the reception and projection ofthe knives. The second part of my invention relates to a system of adjusting-levers operating within the grinding-cylinder, and pivoted to a movable hub, which is made to slide upon the center shaft, adjusting the projection of all the knives uniformly and at one and the same movement. The third part of my invention relates to the construction of the hopper, which is so arranged as to contain the apples in contact with the grinder, while the ends of the open cylinder are left uncovered and accessible to the hand for operating the adj ustin g agencies within.,

The drawing, hereto annexed, shows the cylinder with its headings; also, the knives and the'interior arrangement for adjusting them.

A is the central or driving shaft; B B, the cylinder; G, the knives; and E, the adjusting-levers. The headings F are of cast iron. They are fitted to the cylinder, and then fixed to the shaft by the set-screws G, Fig. 3. In order to hold these segments forming the cylinder in their proper place, and preserve the rotundity of the cylinder, there is a circular trench or groove cast or turned in the heading in which the ends of the segments are fitted. The headings are made open, with radiating arms, as shown in Fig. 2, in order that the adl justing arrangement within may be reached by the hand; and the hopper for containing the apples, hereafter described, is fitted to the circle of the headings, leaving each end of the cylinder accessible for the aforesaid adjustment and for convenience of repairs and other purposes.

In Fig. l the full dark lines C show the dif4 agonal interstices extending from end to end of the cylinder, through which the knives are seen protruding. The dotted lines within exhibit the central shaft A with the hubs D, ad-

justing levers E, and knives C, as seen by a side view, independent of the inclosin g cylinder. Fig. 3, being a vertical section of the whole machine lying in a horizontal position, as when in use, shows the entire arrangement, the hubs D being pressed inward, withdrawing the knives within, even with the surface of the cylinder, and showing the facility of reaching the hand through the open head, and moving the hub upon the shaft outward until the knives project, as desired. The same operation being performed at each end, and the knives being adjusted as desired, the hubs are fixed to the shaft by the set-screws lll. There are clamps which hold the knives and move with them in the adjustment. They embrace the knives on each side, the latter being secured by lateral set-screws, seen at I. There are also set-screws J inserted .in the back edge of the clamps, and reaching the back of the knives. These two latter sets of screws are used in adjusting the knives to a uniform plane in the clamps, and may be .resorted to at any time to c'orrect any imperfection in this uniformity, or for freeing the knives so that any one of them may be removed for repairs and again replaced, but are not ordinarily used for adjusting the projection of the knives. It will be readily seen how any knife may be easily removed and replaced without any derangement of the others. These clamps, which hold the knives and connect themwith the adjusting-arms, are seen in transverse section at K in Fig. 4, as also the manner in which the adjusting-arms are connected with the hubs D. L are the segments composing thecylinder, and G the knives.

Fig. 2 shows the cast-iron head with its open spaces and radiating arms. These headings are cast solid with the bearings M, Fig. l, and are fixed in `Itheir places by the set-screws G. The propelling power is applied to a pulley on the shaft A, where there are a tight and a loose pulley for the convenient starting and stopping of the machine. The hopper containing the apples to beground, 4and which is made to set close to the barrel of the cylinder at the ends,

leaving the full size of the interior of the cyl-` inder open, as before stated, is shown, as when connected with the cylinder at L in Figs. 5, 6, and 7.

Fig. 5 is an end view of 'the same. Fig. 6

is a 'top View, as seen when looking directly down into the hopper; and Fig. 7. is and outside view of the side of the machine Where the feed or throat of the machine is located. There are posts or larms N O, Fig. 5, cast with the circular headings, and situated at the four corners of the hopper and constituting its frame. The `base P, also a part of the heading,'is cast of the shape shown in the gure, to stand in the usual Way upon a floor or pediment raised for the purpose, the Whole area of the bottom being left open for the discharge of the pumice. The feed and throat of the grinder are behind Athe valve R. This valve :is made of Wooden staves, attached at the center to a transverse bar in the rear, which Works on hinges at the sides, as seen at S S. There is a throttle inside of the entrance of the throat, Which,beingacteduponby the set-screWsTTin the fixed cross-bar U, enlarges or contracts the throat for adjusting the feed. The Wooden staves of the valve R are elastic, for the purpose of permitting the passage of pebbles or other hard substances, Which crowd back the opposing stave and thus pass down to the discharge. This arrangement of the feed and discharge is more clearly shown at V in Fig. 5. R is the valve; T, the set-screws in the fixed bar U, by which the feed is adjusted. Thus, the grinding-cylinder, with its convenient and uniform means of adjustment of the knives, and all interior repairs, the Whole grinding-surface being incased, and a fixed hopper conveniently adapted to it, form one entire and complete machine. Nevertheless, itis plain th at my grinding-cylinder, with my device for adjustin g the knives, and with the other appliances I have described, may be used in connection With any other hopper and any other arrangement for feeding so constructed as to leave the ends of the cylinder open for the adjustment of the knives as I have described.

Having thus described my invention and the manner of its operation, what I claim as my invention, and desire to secure by Letters Patent, is-

1. The construction of.the grindingcylinder in Winding segments, as described, with intervening openings or interstices for the projection of the knives, as set forth.

2. The construction of the clamps which hold the revolving knives, as described, With the means of leveling them and xing them by the set-screws to correspond With the rotundity of the cylinder, as herein set forth.

3. The adjusting-levers E, in combination With the sliding hubs D and the clamps which hold the knives, as described, so that, by a simple movement on the center shaftby the hand, all the knives are simultaneously and uniformly adjusted, as herein set forth.

' 4. The hopper, adapted to and combined with the grindingcylinder, as described, and With the device described for adjusting the feed and passing pebbles, as set forth.
